redux-saga-auth v1.0.4

This library is a proposal of redux-saga auth flow.

Reducer must be mounted at { auth } mount point.

Configuration:

import AuthSaga, { reducer as auth } from 'redux-saga-auth';

combineReducers({
  auth
})

saga.run([
  AuthSaga({ 
  saveTokens, //({ user, accessToken, refreshToken }) => throws error on failure
  updateAccessToken, //({ accessToken }) => throws error on failure
  resetTokens // clears tokens above, throws error on failure 
  })
])

Afterlogin|register|logout events are dispatched to use within other sagas to provide the flow you want for your application.

Token storage services must be provided to library sagas.

They might look like:

import invariant from 'fbjs/lib/invariant';
import { AsyncStorage } from 'react-native';

const dataKey = '@TokenData';

const accessTokenKey = `${dataKey}:accessToken`;
const refreshTokenKey = `${dataKey}:refreshToken`;
const userKey = `${dataKey}:user`;

export const restoreTokens = () => {
  return Promise.all([
    AsyncStorage.getItem(accessTokenKey),
    AsyncStorage.getItem(refreshTokenKey)
    AsyncStorage.getItem(userKey).then(JSON.parse);
  ])
    .then(data => ({ accessToken: data[0], refreshToken: data[1], user: data[2] }))
    .catch((error) => {
      console.log(`restore ${dataKey} error.`, error);
      return null;
    });
};

export const saveTokens = ({ user, accessToken, refreshToken }) => {
  invariant(accessToken, "Save tokens: Access token must be present");
  invariant(refreshToken, "Save tokens: Refresh token must be present");
  return Promise.all(
    AsyncStorage.setItem(accessTokenKey, accessToken),
    AsyncStorage.setItem(refreshTokenKey, refreshToken),
    AsyncStorage.setItem(userKey, user)
  );
};

export const updateAccessToken = ({ accessToken }) => {
  invariant(accessToken, "Update tokens: Access token must be present");
  return AsyncStorage.setItem(accessTokenKey, accessToken);
};

export const resetTokens = () => {
  return Promise.all([
    AsyncStorage.removeItem(accessTokenKey),
    AsyncStorage.removeItem(refreshTokenKey),
  ]);
};
